Considering from running little adventures with the pregen character, it's very unlikely that the controller will need to spend a surge in each encounter. Even if he does so, the party has a 6 encounter/day autonomy, easilyBrown Jenkin said:For Controlers with 6 Surges using 1 surge is a 16.666% drain and 2 surges is 33.33%. Figuring a usage level of that much is about right. For defenders with 12 Surges usiung 3 is a 25% drain, using 2 is a 16.66% drain. Yo can't look at 25%, 50%, and 75% hp drains in a combat as a drain of resources since it resets after each encounter.
I really believe that what matter are the Defenders healing surges.
Also from what I've seen so far, players only use surges when they can get the most of it. They won't use a surge that heals 10 HP if they are only 6 HPs short.
What i've seen is the defender spending one surge on the first encounter, 2 surges after the second, 1 after the third, 2 after the forth, and so on, considering balanced encounters by RAW. It's 1.5 surges per encounter. Depending on the party configuration, it will be less than that.
A party that has a defender with 12 surges could go on 9 encounters per day, or more if it has a cleric or another defender.
And all that is for 1st level characters only. We don't know yet if there will be powers or magic items that heal characters without using spending healing surges or let them regain healing surges without an extend resting.
In the worst case scenario, I agree with you, a 1st level party can face 3-6 encounters per day.
